I don't know what value your name has, but streetmachines.com
would be valuable.
Let me clarify the the terminology. In the car world, there is a BIG difference.
A street machine is a modified car or truck, usually American, produced in 1949 or after.
A streetrod is a modified car or truck, usually American, produced
in 1948 or earlier.
Production of cars with full fenders and running boards ceased
after 1948, thus all street machines are considered modern vehicles.
The term "Hotrod" was coined by journalists as a derogatory term for what many saw as "Hot Roadsters". These were primarily
pre-48 Fords, stripped of fenders and running boards. They were
modifed by GI's back from WWII, and were often raced on the dry desert lake beds of California. The cars were then known as "lakes roadsters", and were built primarily for top-end speed.
Many car builders began the sport of drag racing by racing their
roadsters on abandoned runways and the street. The street racers were seen as hellions, and the "Hotrod" term was coined.
Today, any car modified for speed by it's owner can be considered
a hotrod. The term is rarely used for non-American vehicles however, and is almost always associated with drag racing.
